Matlab 2016 fails to run the code

[yuesibihe]

Thank you so much for sharing. I'm learning your code now.But when I run the code, I get an error"Error: File: main.m Line: 31 Column: 19 Creating strings with double quotes is not supported. Use string functions." When I directly “load 73ps_2.mat”;, the error “Warning: While loading an object of class 'Scan': Error: File:Scan.m Line:3 Column:19 Should not be a MATLAB expression.” is reported. Looking forward to your reply!
